Frequent reception of Christ is recommended by the church
Every catholic is obliged to recieve the Eucharist at least once during the Easter season
Some early spiritual writers believed that the petition of Jesus in the Lord's Prayer"give us this day, our daily bread" referred to not only the bread that supposed sustain us, but also the holy Eucharist
The Eucharist encompasses our entire life of faith
In order to receive communion the recipient must be in a state of grace thus free from from grave, this means that the recipient must be free from mortal sin which is forgiven in penance/ reconciliation
In addition to receiving communion, we fast before hand, this reminds us that the Eucharist is not ordinary food and drink
We also must fast against anything that would be unworthy of a follower of Christ. It's also recommended that you dress up for church.
